And if there’s one message I want to deliver to young people like a Tumblr audience is, don’t get cynical. Guard against cynicism. I mean, the truth of the matter is that for all the challenges we face, all the problems that we have, if you had to be — if you had to choose any moment to be born in human history, not knowing what your position was going to be, who you were going to be, you’d choose this time. The world is less violent than it has ever been. It is healthier than it has ever been. It is more tolerant than it has ever been. It is better fed then it’s ever been. It is more educated than it’s ever been.
